on AND WATER WELLJP'UMP;

Application filed; October 6, 1923'. Serial no. 663,977.

The present invention relates to oil and water well pumps, and more particularly to the construction and packing of the same.

An object of the present invention is to the pump rod and the plunger and means for automatically uncoupling the rod when it is raised and for again coupling the rod after it has been lowered into place.

A. still further object of the invention is to provide a pump with latching means for the pump rod for connecting it to the plunger and packing compressing means for the plunger, both of which are operable by manipulation of the pump rod, and to provide means for releasing the packing when the plunger is raised into a predetermined position.

The above and various other objects and advantages of this invention will in part be described in and in part be understood from the following detailed description of the present preferred embodiment, the same being illustrated in the accompanying drawings, wherein:

Fig. 1 is a vertical section taken through an oil and water pump constructed according to the present invention.

Fig. 2 is a fragmentary enlarged section of the upper end of the pump showing the latch rod coupling released from the plunger top.

Fig. 3 is an enlarged transverse section through the latch rod coupling taken on the line of Fig. 1.

Fig. 4 is a fragmentary enlarged section taken longitudinally through the intermediate portion of the pump showing the pump rod connected to the plunger and showing the improved packing between the plunger and the barrel.

Fig. 5 is a transverse section taken through the same on the line 5-5 of Fig. 4, and

Fig. 6 is a transverse section through the upper end of the pump taken on the line 66 of Fig. 2'and looking toward the head of the pump.-

Referring to the drawings 10 designates a pump shell or casing having a top 11 and a bottom 12 which form reducers or nipples for connecting the opposite ends of the shell to the tubing 13 of the'well. Secured in the bottom 12 of the pump is a barrel 14: having therein a foot valve 15 opening upwardly int-o thebarre'l. Slidable within the barrel is a hollow plunger 16 having in its lower end. a lift valve 17 and projecting upwardly through the top of the barrel 14. The barrel 14 1S externally threaded at its upper end and receives a collar or sleeve 18 thereon adapted to be held by the threads in intimate relation with the barrel and forming an enlargement or counter bore in its upper end.

A packing 19 of suitable compressible material is placed within the counter bore or interior of the collar 18 for" contact with the exterior surface of the plunger 16, and a packing gland 20 is fitted in the top of the sleeve or collar 18 and against the packing 19 for compressing the latter. The gland 20 had a head 21 upon its upper end" provided at opposite sides with pairs of ears 22 between which are pivoted latch levers 23 projecting downwardly in the shell or casing 10 and overlapping the upper end of the collar 18. The collar 18 has downwardly inclined ratchet teeth 24 and the levers 23 are provided with upwardly inclined ratchet teeth 25 adapted to mesh with the teeth 24 and hold the gland 20 in adjusted position when forced down. The upper ends of the latch levers 23 are urged outwardly by springs 26 which are interposed between the upper ends of the levers 23 and the head 21 of the packing gland. These springs 26 yieldingly interlock the levers 23 and the sleeve or collar 18.

The plunger 16 has a hollow enlarged plunger top 27 which overhangs the head 21 of the packing gland and which at its upper end has an inturned annular flange 28 adapted to releasably interlock with a pair of jaws 29- normally spread apart by springs 30. These jaws 29 comprise a pair of Vertically disposed bars which are fitted in a hollow shell or casing 31 secured by threads or the like to the lower end of the pumping rod 32. The shell 31 has lateral slots 33 therein and the bars 29 have intermediate enlargements in the lower ends of which are formed slots 84 of a width adapted to snugly receive the flange 28 of the plunger head therein so as to couple the head with the bars 29. The opposite ends of the enlargement of the bar 29 are provided with inclined or cam shoulders 85 the lower ones of which are adapted to engage the top of the flange 28 for contracting the bars 29 and permitting the same to pass through the opening in the flange 28 until the slot 34 reaches the flange when the bars 29 are expanded by their springs 30 to interlock the bars 29 with the flange 28.

The upper ends 35 of the enlargements are adapted to engage the upwardly converging inner wall 36 .of the top ll of the pump when the rod 34 is elevated for contracting the bars 29 and releasing the same from the flange 28 so that the pump rod may be raised without Withdrawing the plunger.

When it is desired to tighten the packing 19 between the barrel 14 and the plunger 16, t

it is only necessary to raise and lower the pumping rod with the plunger head 27 and impact the latter against the gland head 21 for driving the gland into the collar 18 and against the packing 19. As the gland is moved inwardly against the packing the latch levers 23 follow the gland and interlock in consecutively new positions to hold the gland from springing outwardly when the force of the impact is dissipated. The gland may be Very quickly released by contracting the upper ends of the latch levers 23 to release the lower ends of the same from the collar 18.

It is of course understood that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claim.

What is claimed is:

In a packing device of the class described the combination of a tubular member having a passageway therein, a plunger reciprocable in said passageway, said tubular member at an end thereof having a sleevelike portion in spaced relation with the plunger to provide an annular chamber about the plunger in the slcevelike portion, packing material in said annular chamber, said sleeve-like portion on the exterior thereof having teeth, a gland slidable in the annular chamber against said packing to compress the same, means formed on the plunger to impact said gland to cause the same to compress said packing, detent arms pivotally mounted intermediate their ends directly on said gland having teeth at the ends thereof in facing relation with the gland for cooperation on the teeth of the sleeve-like portion above mentioned, to prevent release of the packing when the gland has forced the same into a packed relation in the annular chamber, and spring means carried by the gland at the opposite ends of said detent arms operating on the latter to force the teeth of said arms into engagement with the teeth of the sleeve-like portion.-
